We observe that the evolution equation for the torsion was derived in
[1]}. Using our Laplacian formulation, we can readily rederive this result:
\(\partial _t T=\partial _t i \partial \omega =- i \partial \partial ^\dagger _{\omega , \Omega } \partial \omega =-\partial \partial ^\dagger _{\omega , \Omega } T.\)
